Subject: ARM: dts: am43xx-epos-evm: Keep DCDC3 regulator on in suspend to memory
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=177425ef586a932b968d4adf6a258da61b0ae727;p=linux.git

ARM: dts: am43xx-epos-evm: Keep DCDC3 regulator on in suspend to memory

When going to suspend to ram mode (or rtc-only mode), the DDR regulator
must be told to stay on, else this rail will go down when the PMIC_EN
signal is deasserted.
